The TAIHO Connecting Rod Bush (STD, P040HS) is a precision-manufactured engine component designed to support the small end of the connecting rod and reduce friction between the piston pin and the rod during engine operation. This standard size pin bushing provides a durable, low-friction surface that improves engine reciprocating motion and helps reduce internal wear.

This set is typically sold as a set of four bushes for all cylinders where applicable, and is suitable for engine rebuilds, overhauls, and maintenance work where this bush size is required. TAIHO products are engineered for high quality and consistent performance.

Key Features

• Standard size connecting rod / piston pin bushing by TAIHO

• Reduces friction and wear at the small end of the connecting rod

• Precision-made for consistent quality and fit

• Supports smoother engine operation and reduced internal stress

• Suitable for engine rebuilds, maintenance, and repair

Detailed Technical Specifications

Commonly this type of bushing is used in diesel engines where a standard small-end / pin bushing set is required, made to fit commonly referenced OEM requirements.

Function Overview

A connecting rod bush (also called a piston pin bushing) is installed in the small end of the connecting rod to provide a bearing surface for the piston pin (wrist pin). It minimizes metal-to-metal contact and distributes load during engine reciprocating motion, contributing to smoother engine performance and reduced wear.
